The content of NH 4 -N as well as NO 2 -N in the effluent is generally less than 2 mg/l. Some highly concentrated ,wastewater, is fed directly into the second stage in order to obtain rather complete denitrification. So the NO 3 -N-concentration in the effluent can be kept below 20 mg/l (85% nitrogen ,removal,) mostly.
